Can you show me how you got to the answer?
Thanks:)
(3 - √3)/(2 - √3)
Using conjugate of denominator,
(3 - √3)(2 + √3) / (2 - √3)(2 + √3)
= (6 + 3√3 - 2√3 - 3) / (4 - 3)
= (6 - 3 + √3)/1
= (3 + √3)
Ideally, you want to get rid of the root in the denominator, which you can do my multiplying the top and bottom by the conjugate.
For a+b, the conjugate is a-b.
So (3-â3)/(2-â3) = [(3-â3)(2+â3)]/[(2-â3)(2+â3)]
This gives (9+5â3)/(1)
So the answer is 9+5â3
It's already solved. If you meant to say rationalize the denominator, then
(2 â3)/(2 â3) (3 - â3)/(2 - â3) =
(6 - 2â3 3â3 - 3)/(4 - 3) =
(3 â3)/1 =
3 â3
Let under-root 3 be x, then
your question becomes
(3-x)/(2-x)
Now rationalise it. That is multiply the numerator and dinominator by (2+x)
Then it becomes (3-x)(2+x)/(2-x)(2+x)
You will get
(6+3x-2x-x^2)/(4-x^2)
here you will get
(6+x-x^2)/(4-x^2)
Now if you put the valu of x as root3
Then you will get
The answer as3+root 3
Note x^2 means x raised to power 2
And root 3 raised to power 2 is 3only.
6-3â3-2â3+3=
9-5â3
To get the exact answer to this kind of problem, multiply the numerator and denominator by
2+sqrt(3)
That will make the sqrt(3) terms drop out of the denominator, and you will just have the numerator to worry about:
(3-sqrt(3))/(2-sqrt(3) * (2+sqrt(3)/(2+sqrt(3)) = (3-sqrt(3))*(2+sqrt(3))/(4-3) =
(3-sqrt3)*(2+sqrt(3) = 6 - sqrt(3) -3 = 3 - sqrt(3)
In all such problems, if you have a-sqrt(b) in the denominator, multiply denominator and numerator by a+sqrt(b).
If you have a+sqrt(b) in the denominator, multiply by a-sqrt(b).
That way the messy terms will drop out of the denominator and you just have to deal with them in the numerator.
(3 - â3)/(2 - â3)
=> Rationalise the denominator, i.e.
(3 - â3) * (2 + â3)
---------------------
(2 - â3) * (2 + â3)
=> Use the difference of 2 squares in simplifying the denominator & also apply FOIL in removing the parentheses at the numerator, then you'll obtain
6 + 3â3 - 2â3 - 3
(2)² - (â3)²
=> Collect like terms at the numerator, i.e.
(6 - 3 + 3â3 - 2â3)/(4 - 3)
= (3 - â3)/1
= 3 - â3 ...Ans.

Hi there. Well it seems as if the people who have got the correct answer are the ones who have been given the poorest ratings. The answer is 4.732 or 3 + sqrt3.
(3 - â3)/(2-â3)
Rationalising the denominator we get
(3 - â3)(2+â3)/{(2-â3)(2+â3)}
={3 (2+â3)â â3(2+â3)}/{(2²-(â3)²}
={(6+3â3)â (2â3+3)}/{(4â 3)}
={6â3+3â3â 2â3)}/{(4â 3)}
={3+â3}/{1}
=3+â3
